Short-term administration of steroids does not affect postoperative complications following liver resection: Evidence from a meta-analysis of randomized controlled trials.

AIM: Although perioperative short-term administration of steroids can attenuate surgical stress response following liver resection, there is no consensus concerning the effect on postoperative complications. This study aims to use meta-analysis to quantitatively investigate the effect of perioperative short-term administration of steroids on postoperative complications following liver resection.
METHODS: A systematic published work search was performed to detect randomized controlled trials (RCT) assessing the effect of perioperative short-term administration of steroids on outcomes following liver resection. Parameters of surgical stress, hospital stay and postoperative complications were analyzed. Two authors independently assessed study quality and extracted data. All data were analyzed using RevMan version 5 and meta-analyses were performed using a random-effects model.
RESULTS: Five RCT published between 2001 and 2011 containing a total of 379 patients were eligible for final analysis. Serum total bilirubin, interleukin-6 and C-reactive protein were significantly lower in the steroid than in the control group on postoperative day 1 (P = 0.02, 0.004 and 0.02, respectively). There was no difference in duration of hospital stay between the steroid and control group (P = 0.37). The analysis of end-points including infective complications (odds ratio [OR], 0.95), wound complications (OR, 0.67), bile leakage (OR, 0.58) and overall complications (OR, 0.50) revealed no difference between steroid administration and no treatment. There was no postoperative death or adverse effect attributable to steroid treatment in all patients.
CONCLUSION: On currently available evidence, short-term administration of steroids does not increase incidence of complications in patients undergoing liver resection.
